I don't know about other countries.. But for Singapore,
First of, you gotta take currency exchange into account.
Titan X in SLS (Singapore) the price you quoted, 1799, is in Sgd which is around 1340 Usd
Secondly, there's the Gst (VAT taxes) and thirdly, there's the shipping cost and lastly, the profit the stores want to make.
All in all if you want to cut off the middle man (the stores), there's Amazon. You can't escape the Gst (7% currently) but it's definitely cheaper than buying from stores here, and there's international free shipping to Sg. But of course, you gotta bare in mind that there's no local warranty if you buy it from Amazon.
